WITSML Office Aggregrator From Petrolink

WITSML in a Real-Time Operations Centre From Petrolink

Petrolink: WITSML Architecture This solution sees the WITSML server located in the company DMZ, which is probably in the same physical location as the operations offices (but may not be for some who have centralised access management to the internet) Internal users can access plots at fast speed, and these plots can also e accessed externally as the DMZ is also open to the internet Data can also be forwarded to the data acquisition company through a dedicated VPN (virtual private network) – in the case where an independent satellite link for that company is not in use These independent satellite links add extra cost to the operation, since if the service company pays for it the cost is certain to be passed on the Operator one way of the other This hybrid solution incorporates the advantages of both the fully outsourced and internal solutions, but may not be allowed because of security concerns

Kongsberg: Lessons learned Global infrastructure done right allows access data for everybody in the organization regardless of location Global infrastructure must be scalable and be built to handle increasingly large amounts of data The true value of WITSML and a global infrastructure comes when the SOA is managed and deployed with an enterprise perspective (Contracts, Vendors, Infrastructure, Connectivity) Global infrastructures require changes to governance mechanisms (security, process, etc.) Work Processes, Environments, Data Management are all interconnected and should be designed together. WITSML is a standard that enables real-time data workflows for the intelligent oilfield Service and Software Providers as well as Clients can produce and consume real-time data using WITSML More details on this established well and drilling data management standard can be found online at WITSML.ORG

What are WITSML Benefits for BP? Simplify the award of contracts to service companies Enable remote working and automation Encourage adoption of multi-service-company solutions Speed up deployment of technical applications Improve health, safety, and environmental factors Improve operational efficiency Help address the “big crew change”

BP: WITSML inter-operability testing Energistics is starting compliance testing of WITSML products in 2008. Inter-operability between different software solutions is a major benefit of WITSML. As an interim measure, BP is conducting its own inter-operability testing in a dedicated WITSML laboratory hosted for us by SAIC in Aberdeen. We are inviting our principal vendors to submit products for inter-operability testing prior to deployment. The WITSML laboratory will be used also as a diagnostic environment during operations. The first activities of the WITSML laboratory support UK North Sea and Gulf of Mexico operations.
